Everyone says they develop with Spring, but for a beginner developer who just learned the basics of Java, the backend world and Spring technology felt scary. I started studying development for the first time at the age of 27 as a non-major, and I had no idea where to start, but I am slowly finding my way after listening to the instructor's lecture. Even an instructor who has studied for a long time says that he doesn't know everything about Spring, so it seems that Spring is a technology that contains a lot of depth and a vast amount. I am still a beginner who has only taken the introductory-basic lecture, but I would like to thank you for giving me hope through the lecture as I find what I want to do and challenge myself little by little. I will continue to study hard and become a developer who writes good code. Thank you, instructor. Be happy!
